Technical Field

[0001] The utility model relates to a four-side processing fixture for a gland used in the field of mechanical processing. Background Art

[0002] Existing machining fixtures are designed for specific product structures, and a single setup can only process one or two workpiece surfaces, resulting in low efficiency. Frequent fixture changes increase production costs and time in the production of high-variety, low-volume products. The complex operation of some fixtures can lead to operator errors, compromising machining efficiency and quality. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a four-sided processing fixture for a gland, which can realize fast and efficient clamping of general-purpose workpieces and can realize multi-sided processing of workpieces.

[0004] A technical solution to achieve the above object is: a four-side processing fixture for a gland, comprising a base plate, a fixture screw and a pressing block;

[0005] A number of blind holes are provided on the base plate, and the blind holes are arranged in a straight line along the base plate at equal intervals. Clamp screws are inserted into the blind holes, and pressure blocks and fasteners are sleeved on the clamp screws. Each workpiece to be processed is set on the base plate, located between two clamp screws, and the pressure block spans the top surface of any two adjacent workpieces and is fastened by fasteners to press the workpieces against the surface of the base plate. The base plate is connected to the flipping mechanism and can be flipped around the central axis in the length direction of the base plate under the drive of the flipping mechanism.

[0006] Furthermore, the pressure blocks are divided into middle pressure blocks and two end pressure blocks. The two end pressure blocks are pressure blocks that are sleeved on the clamp screws at both ends of the blind holes arranged in a straight line, and the rest are middle pressure blocks. The middle pressure blocks are connected across the top surfaces of any two adjacent workpieces. One side of the two end pressure blocks is pressed onto the top surface of the workpiece, and the other side is supported by a support column arranged on the base plate.

[0007] Furthermore, a marking point for marking the workstation where the workpiece is placed is provided at the midpoint of the line connecting any two adjacent blind holes.

[0008] Furthermore, four positioning pins are provided on the surface of the bottom plate corresponding to each work station.

[0009] Furthermore, a processing window leading to the bottom of the workpiece is opened on the bottom plate corresponding to the workpiece placement position.

[0010] Furthermore, the flip mechanism is positioned and locked at a flip angle of 90 degrees.

[0011] The utility model provides a four-sided processing fixture for a gland, which has the following advantages:

[0012] 1. The present application can clamp multiple workpieces at one time and can process the threaded holes on both sides of the workpieces at the same time. If necessary, four surfaces can be processed at the same time.

[0013] 2. The clamp can be used for clamping most types of workpieces without the need of designing different clamps for different types of workpieces.

[0014] 3. The clamping operation is simple and efficient.

[0015] 4. The workpieces can be flipped over, so that the four directions of the workpieces can be processed. BRIEF DESCRIPTION OF DRAWINGS

[0016] Figure 1 It is a side view of the four-surface processing clamp for a cover of the present application.

[0017] Figure 2 It is a plan view of the four-surface processing clamp for a cover of the present application. DETAILED DESCRIPTION

[0018] In order to better understand the technical scheme of the present application, the following will be described in detail through specific embodiments:

[0019] Please refer to Figure 1 and Figure 2 The four-surface processing clamp for a cover of the present application is used for processing threaded holes on the front and rear end surfaces of a workpiece.

[0020] The bottom plate 1 is provided with a row of five blind holes, which are arranged in a straight line along the direction of the bottom plate 1 at equal intervals. The clamp screw 2 is inserted into the blind hole. The pressing block 3 and the fastener 4 are sleeved on the clamp screw 2. The clamp can clamp five workpieces 5 at one time.

[0021] Among them, the pressing block is divided into middle pressing blocks 31 and end pressing blocks 32. The end pressing blocks 32 are the pressing blocks sleeved on the clamp screws 2 at both ends of the straightly arranged blind holes, and the rest of the pressing blocks are the middle pressing blocks 31. The middle pressing blocks 31 are connected to the top surfaces of any two adjacent workpieces 5. The end pressing blocks 32 are pressed on one side of the top surface of the workpiece 5 and are supported on the other side by the support column 6 provided on the bottom plate 1. The support column can ensure the balance of the end pressing blocks 32.

[0022] In order to realize multi-sided processing of the workpiece, the base plate 1 is connected to the flipping mechanism, and can be flipped around the central axis in the length direction of the base plate under the drive of the flipping mechanism. Usually, the surface facing directly upward is the surface to be processed facing the processing tool by default. For example, the top surface of the workpiece is processed first. After the top surface is processed, the flipping structure is flipped, and the front end face and the rear end face of the workpiece are turned directly upward in turn for processing. If there is something that needs to be processed on the bottom surface of the workpiece facing the base plate, a processing window can be opened at the corresponding position on the base plate as needed, and then the surface is flipped to the top for processing. The flipping mechanism is positioned and locked at a flipping angle of 90 degrees to ensure that the base plate remains stable and reliable when processing in all directions.

[0023] In some necessary cases, the four sides of the workpiece can be processed simultaneously by processing tools in four directions.

[0024] Furthermore, the midpoint of any two adjacent blind holes is marked with a dot for marking the workpiece placement position. Four locating pins are located on the baseplate surface, corresponding to each workstation. This structure enables operators to quickly and accurately locate workpieces and quickly set them in the clamping position, improving production efficiency.

[0025] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
