The clamping device includes a guide rail, and movable clamping plates are provided at both ends of the guide rail. The base part is clamped between the two movable clamping plates. A suction device is provided below the clamping device, and the suction device includes an upper plate. This utility model uses a motor to drive the movable clamping plates to clamp the base part. An upper plate is provided below the movable clamping plates, and a lower plate is provided below the upper plate. A cylinder drives the lower plate to rise and fall, causing the pull rod in the upper plate to move the sealing gasket up and down within the upper plate. When the mesh suction cap contacts the base part, a sealed space is created. The cylinder drives the pull rod to pull downward, adsorbing the base part above the outer column and fixing it. This prevents the base part from being restricted by its shape and size, and, in conjunction with the movable clamping plates, makes it more stable.

Description

Technical Field

[0001] This utility model relates to the field of fixture equipment technology, specifically a machining fixture for base parts. Background Technology

[0002] Base components are typically used to secure equipment. However, due to their varying sizes and shapes, they are often difficult to fix during machining. A common method is to clamp the component from both sides. If the surface of the component is uneven, the clamping force is usually increased for stability. This method, however, can easily lead to unstable fixing or uneven stress during machining, resulting in defective parts, increased processing costs, and reduced profits. Therefore, we propose a machining fixture for base components. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a machining fixture for base parts.

[0004] The technical solution of this utility model is: A machining fixture for a base part includes a clamping device. The clamping device includes a guide rail, and movable clamping plates are provided at both ends above the guide rail. A base part is clamped between two of the movable clamping plates. A pneumatic suction device is provided below the clamping device. The pneumatic suction device includes an upper plate, on which a plurality of sets of outer columns are fixedly installed at equal intervals. A lower plate is provided below the upper plate, and a plurality of sets of pull rods are fixedly installed at equal intervals above the lower plate. The pull rods are inserted into the outer columns. Cylinders are symmetrically fixedly installed at the bottom of the lower plate.

[0005] As a preferred technical solution of this utility model, a sealing gasket is fixedly installed above the pull rod, the shape and size of the sealing gasket are adapted to the interior of the outer column, a mesh suction cap is fixedly installed above the outer column, and two sets of support legs are symmetrically slidably connected to both sides of the lower plate, the support legs are fixedly installed at the bottom of the upper plate.

[0006] As a preferred technical solution of this utility model, a base is fixedly installed at both ends of the guide rail, and a motor is fixedly installed on the top of the base. Two lead screws are threadedly connected to the output shaft of the motor. The two lead screws are fixedly connected and have opposite threads. The bottom of the two movable clamps are respectively threadedly connected to the two lead screws.

[0007] As a preferred technical solution of this utility model, the guide rail is fixedly installed with a fixing plate at both ends and the middle, the lead screw is rotatably installed on the fixing plate, the guide rail is provided with sliding grooves on both sides inside, and the sliding blocks are symmetrically fixedly installed on both sides below the movable clamping plate, and the sliding blocks are slidably connected to the sliding grooves.

[0008] As a preferred embodiment of this utility model, a connecting rod is fixedly installed on one side of the movable clamping plate, and a clamp is threaded onto the connecting rod.

[0009] As a preferred embodiment of this utility model, the movable clamp is provided with symmetrical grooves on both sides below, the mesh suction caps are provided on both sides of the lead screw, and the diameter of the grooves is larger than the diameter of the mesh suction caps, and the distance between the mesh suction caps is larger than the thickness of the movable clamp.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a motor-driven movable clamping plate to hold the base part. An upper plate is located below the movable clamping plate, and a lower plate is located below the upper plate. The lower plate is driven to rise and fall by a cylinder, causing the pull rod inside the upper plate to move the sealing gasket up and down within the upper plate. When the mesh suction cap comes into contact with the base part, a sealed space is created. The cylinder drives the pull rod to pull downward, adsorbing the base part onto the outer column and fixing it. This ensures that the base part is not restricted by its shape and size, and works more stably with the movable clamping plate. Attached Figure Description

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.

[0015] Please see Figure 1-4 This utility model provides a technical solution: A machining fixture for a base part includes a clamping device 1. The clamping device 1 includes a guide rail 11. Movable clamping plates 14 are provided at both ends of the guide rail 11. A base part a is clamped between the two movable clamping plates 14. A suction device 2 is provided below the clamping device 1. The suction device 2 includes an upper plate 21. Several sets of outer columns 24 are fixedly installed on the upper plate 21 at equal intervals. A lower plate 22 is provided below the upper plate 21. Several sets of pull rods 26 are fixedly installed on the upper plate 22 at equal intervals. The pull rods 26 are inserted into the outer columns 24. Cylinders 23 are symmetrically fixedly installed at the bottom of the lower plate 22. The cylinders 23 are fixed to the ground or support legs 28 by other fixing devices.

[0016] A sealing gasket 27 is fixedly installed above the pull rod 26. The shape and size of the sealing gasket 27 are adapted to the inside of the outer column 24. A mesh suction cap 25 is fixedly installed above the outer column 24. Two sets of support legs 28 are symmetrically slidably connected to both sides of the lower plate 22. The support legs 28 are fixedly installed at the bottom of the upper plate 21. The upper part of the mesh suction cap 25 is made of a relatively soft and elastic material, which can deform according to the shape of the bottom surface of the base part. When the base part is placed on the guide rail 11 and squeezed, it can maintain good air tightness. The sealing gasket 27 is inserted and matched with the inside of the outer column 24. The material of the sealing gasket 27 is relatively soft and elastic, ensuring excellent air tightness inside the outer column 24.

[0017] The guide rail 11 has a base 110 fixedly installed at both ends and below. A motor 12 is fixedly installed on the top of the base 110. Two lead screws 13 are threadedly connected to the output shaft of the motor 12. The two lead screws 13 are fixedly connected and have opposite threads. The two movable clamping plates 14 are threadedly connected to the two lead screws 13 respectively. When the motor 12 drives the lead screws 13 to rotate, the movable clamping plates 14 will move towards each other due to the opposite threads, thereby clamping the base part a.

[0018] The guide rail 11 is fixedly mounted with a fixed plate 111 at both ends and in the middle. The lead screw 13 is rotatably mounted on the fixed plate 111. The guide rail 11 has a sliding groove 18 on both sides inside. The movable clamping plate 14 is symmetrically fixedly mounted with sliders 17 on both sides below. The sliders 17 are slidably connected to the sliding grooves 18 to restrict the movable clamping plate 14 and keep it able to move stably horizontally.

[0019] A connecting rod 15 is fixedly installed on one side of the movable clamping plate 14. A chuck 16 is threaded onto the connecting rod 15. The chuck 16 can be replaced with a suitable one according to the size and shape of the base parts, and then fixed onto the connecting rod 15.

[0020] The movable clamping plate 14 has symmetrical grooves 19 on both sides below it, and the mesh suction caps 25 are located on both sides of the lead screw 13. The diameter of the grooves 19 is larger than the diameter of the mesh suction caps 25, and the distance between the mesh suction caps 25 is larger than the thickness of the movable clamping plate 14, so that the movable clamping plate 14 will not be obstructed by the mesh suction caps 25 when it moves horizontally.

[0021] In this embodiment, when the operator uses this device, the base part a is placed between the two movable clamping plates 14, and the motor 12 is turned on to drive the lead screw 13 to rotate, so that the movable clamping plate 14 connected to it moves horizontally to clamp the base part a. When the base part a is placed above the guide rail 11, its bottom will be squeezed against the mesh suction cap 25, thereby forming a sealed space inside the outer column 24. The cylinder 23 is turned on to drive the lower plate 22 to descend, so that the pull rod 26 drives the sealing gasket 27 to move downward. Since the sealing gas inside the outer column 24 is limited, when the sealing gasket 27 is pulled, the bottom of the base part a will be firmly adsorbed above the mesh suction cap 25, thereby fixing it.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
